    • An article of an eye wear worn externally upon an eye, having an article which article comprises a wavelength transmission blocker. The wavelength transmission blocker has a lutein assimilated therein for preventing radical damage in the eye. The wavelength transmission blocker is sized and configured to maximize visual acuity and block at least 80% of light wavelengths throughout a blue light spectrum set in a range from about 400 nm to about 510 nm. Preferably, the wavelength transmission blocker is operative to block substantially 100% of light wavelengths lower than 420 nm, and to block about 99% light wavelength at 420 nm and about 20% of light wavelength at 510 nm. Preferably, the wavelength transmission blocker blocks a gradually reduced percentage of light wavelengths between 420 nm to 510 nm. The wavelength transmission blocker is also operative to block a portion of light wavelengths between 510 nm to 650 nm.
    • 戴在眼睛外部的眼睛磨损物品,其具有包含波长传递阻滞剂的物品。 波长传递阻断剂具有在其中同化的叶黄素,以防止眼睛中的自由基损伤。 波长传输阻挡器的尺寸和构造被设计成使视力最大化并且阻挡在约400nm至约510nm范围内的整个蓝色光谱中的至少80%的光波长。 优选地,波长传输阻挡器可操作地阻挡基本上100%的低于420nm的光波长,并且阻挡在420nm处约99%的光波长和在510nm处约20%的光波长。 优选地,波长传输阻断剂阻挡420nm至510nm之间逐渐减小的光波长百分比。 波长传输阻挡器还可操作以阻挡510nm至650nm之间的一部分光波长。

    • A computer-based engineering design system to design a part, a tool to make the part, and the process to make the part. The design system has a processor and a memory. The memory stores feature templates, each feature template being a representation of a primitive object having a form and a function. Each feature template is indexed by the function of the primitive object and includes a representation of a primitive geometric entity having the form of the primitive object. Each feature template can include information relating to a tool to make the primitive object and a process to make the primitive object. The design system also includes an input device for receiving a request to design the part. This request includes one or more predetermined functions that the part performs. A core design module, executable by the processor, designs the part, the tool to make the part and process to make the part by accessing the plurality of feature templates in the memory to locate one or more primitive objects that perform the one or more predetermined functions.
